National Building Code Sectional Committee, CED 46
Each Part or Section of the National Building Code of India gives the definitions of the special terms used in it. These definitions may be found in the clause ‘Terminology’ normally placed immediately after the ‘Scope’ in each Part/Section. However, users may find this Part very convenient for reference as it gives the alphabetically arranged list of terms defined in all the Parts/Sections, along with the location of the definition. It may also be noted that in some cases like in Part 3 ‘Development Control Rules and General Building Requirements’ and Part 7 ‘Construction Management, Practices and Safety’ of the Code, these have been placed in other appropriate clauses rather than after ‘Scope’ considering the suitability and convenience afforded therefrom.
In this revision, this Part has been updated to cover the various terms actually covered in different Parts/Sections in this revision of the Code.
